Fix field order inconsistency between IPv4 and IPv6 responses

- Standardize object property order for both IPv4 and IPv6 lookups
- Order is now consistent: range, country, region, eu, timezone, city, ll, metro, area
- Previously IPv6 had different order: range, country, region, city, ll, metro, area, eu, timezone
- All tests passing
